DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stake magazine supplying device for supplying a stake magazine containing a plurality of electronic components such as switches, volumes, capacitors, etc. to a shooter that sends it to an automatic electronic component assembly machine, etc. It is something.

Conventionally, it has been considered to use an automatic electronic component assembly machine to incorporate this type of electronic component into a printed circuit board. When supplying electronic components to such an automatic electronic component assembly machine, prepare in advance a number of stake magazines containing multiple electronic components, and send one stake magazine to the shutter of the component supply device. The electronic components can be taken out one by one from this stack magazine and supplied to an automatic electronic component assembly machine.

A stake magazine supply device that sequentially supplies a plurality of stake magazines to a shooter is such that a plurality of stake magazines are easily stacked vertically, and the lowest stake magazine is easily removed from the rack by a magazine supply arm. It is conceivable that the liquid be extruded and also supplied into the shooter.

However, in a stationary magazine supply device with such a configuration, when the magazine supply arm returns to its original state, the multiple stationary magazines in the rack suddenly fall, causing the electronic components inside the stationary magazines to fall. There was a risk that the magazine would be damaged or the lowermost stationary magazine would be seated at a position deviated from the predetermined push-out position.

Therefore, the present invention provides a storage rack for stacking a plurality of stake magazines, and a storage rack in which the height of the top part is set to be lower than the height of the lowest stake magazine in the storage rack, and only the lowermost stake magazine is stacked. a magazine supply arm configured to push out the magazine from the storage rack and supply it to the shooter, and to receive at the top part the lower surface of the lowest stack magazine among the remaining stacked magazine magazines in the storage rack; After the supply arm pushes out the lowest stake magazine from the storage rack, it is raised to support the remaining stake magazines in the storage rack, and after the magazine supply arm returns to its original position, it is lowered to push out the storage rack. The stick magazine supply device is equipped with a magazine receiving member for lowering the stick magazine therein. This results in
When the magazine supply arm returns to its original state, the multiple stake magazines in the storage rack will not fall suddenly but will gradually descend slowly, thereby preventing the terminals of the electronic components inside the stake magazines from being bent. This prevents the stick magazine from falling or becoming out of alignment, and allows the lowermost stick magazine to be accurately placed at a predetermined push-out position. In addition, when the magazine supply arm supplies a stake magazine to the shooter, the magazine supply arm is formed to a length that allows its tip to push out an empty stake magazine in the shooter, making it easier to replace the stake magazine in the shooter. It can be easily performed with a simple configuration.
